Skeletal implant

Skeletal implant of the type to be used to connect at least two elements of a skeleton. The skeletal implant includes a first part adapted to be connected to at least one of the at least two elements of the skeleton. A second part is adapted to be connected to another of the at least two elements of the skeleton. A variable volume element is adapted to move the first and second parts with respect to each other. A high-pressure chamber supplies fluid to the variable volume element. A low-pressure chamber receives fluid from the variable volume element. A recharging variable volume element is adapted to communicate with the high-pressure chamber and the low-pressure chamber. The recharging variable volume element is responsive to displacements of corporal parts of a user and recharges the high-pressure chamber with fluid. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
